The death toll from the destructive Texas flash floods rose to 51 Saturday, with hundreds of rescuers combing through water and debris to find missing people, including children from a summer camp. The majority of fatalities were recorded along Guadalupe River basin in Kerr County.

Heavy rain poured over parts of central Texas, dumping more than a month's worth of rain for places like San Angelo.

Meteorologists say incredible amounts of moisture in the air fueled a storm that moved slowly over central Texas, creating conditions for fatal flash floods.
